Why people use it
Any plan, back to 2010
Hourly, daily, weekly, bi-weekly or monthly buys, starting any year since 2010. Rivals replay a year; we replay the whole history.
Your average cost, visible
Four charts show invested vs value, your average cost against the market price, the Bitcoin you stacked, and the stretches spent under water.
No account, no tracking
No sign-up, plans stored on your phone only, and ads are non-personalized. Your data is not the product.
Learn as you go
Plain-language explainers on every result, in words anyone can follow. Past data and arithmetic, never predictions.
In the app
The calculator
Pick an amount, a rhythm and a start year. Get total invested, Bitcoin that would have bought, and value at the end, with the method shown on the result.
Four charts
Growth (invested vs value), average cost vs market price, Bitcoin accumulated, and underwater periods with your longest stretch marked.
Converters
Sats to Bitcoin, Bitcoin to dollars and euros, at the live price. Pure math, no sign-up.
Shareable result cards
Every result becomes a clean card you can share. The link replays your exact plan for whoever opens it.
Saved plans
Save plans on your device and revisit them any time. Everything stays on your phone.
Coming next
A habit goal planner (time to a Bitcoin target at your pace) and the basics quiz are in the roadmap for the next releases.
What it costs

The complete calculator, unlimited runs, all four charts, converters and saved plans. Supported by non-personalized ads.

Questions
Is BitcoinSaving on the App Store yet?
The TestFlight beta opens soon. Leave your email on this page and we will send your invite the moment it opens. The App Store release follows the beta round.
Does the app hold or buy Bitcoin?
No. BitcoinSaving is a calculator and education app. It replays past prices and does the math on plans you describe. There is no wallet, no trading and no buying inside the app.
Do I need an account?
No. There is no sign-up and no sign-in. Your saved plans stay on your phone, and the app does not track you across other apps.
Is the app free?
Yes. The app is free and supported by non-personalized ads. A Premium unlock with extra power features is planned for a later update as a one-time payment.
